To ttt/Z w/tom/ t wwf/y concern:

Be it known that I, EDWARD WACKER- HAGEN, a citizen of thc UnitedStates, and a resident of Fort Lee, in the State of New Jer* sey, haveinvented certain new and useful 1mprovements in Looms, of which thefollow* ing description, taken in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

My invention relates to improvements in looms, and has for its object toprevent the sticking of the warp threads or completed web to the frontand rear glass rods, occasioned by the presence of excessive moisture inthe atmosphere.

In the weaving of silk fabrics, as in the weaving of other fabrics, theoperation is unfavorably affected by the humidity of the atmospherewhich often prevails in the factory either through natural or artificialcauses and which is either too high or too low for the best results inweaving. At such times the warp adheres to the rear glass bars and theweb adheres to the front bar in a way to produce a bitching motionrather than a regular even progress of the warp and of the web overthese bars, with the result that the weftthreads are laid unevenly inthe web. My improvement remedies this difficulty.

It is essential to good weaving that the warp should pass the rear glassbars, as the web should pass the front glass bar, evenly and regularlywith each stroke of the batten, and to secure this the regulatonroll o rclothbeam C, as the case may be, is actuated by a ratchet which secu resthis regulator intermittent motion but if from the action of humidity inthe air or other cause the warp-threads or the web adhere to the barunduly the regular intermittent motion essential to good weaving is notobtained, and the cloth-beam or regulator-roll continues its motion, butthe web will pass one or two or three strokes of the lathe without anyprogress of the warp or of the web over the bars. The result is that theweft is laid and beaten up unevenly, and the web is of uneven texture atsuch a point, unduly compact for a few threads of the lling, and thentoo loose.

l Vth looms making high-grade silk fabric it has been found necessary tostop work whenever the humidity of the atmosphere exceeded about sixtyper cent. The loss entailed both to the weavers and to the manufacturerswas enormous, and the time when this loss would be inflicted could notbe foretold, since it is wholly dependent upon the state of the weather.By this invention AI have overcome this diflculty.

In the drawings forming part of this specication, Figure l is a sideelevation of a loom, illustrating my invention, parts being shown insection. Fig. 2 is a plan elevation rof a modification of my device.Fig. is a View, partly in section, further illustrating saidmodification.

In the form shown in Fig. 1 my invention consists in a slat of wood A,fastened to the lower side of the lathe, projecting forward from itabout two inches in such wise as to tap the web a light blow and pressit outward from a straight line about two inches at a point below thefront glass bar and between it and the regulator-roll. The warp-beams orwarp-rolls weighted for tension are not shown in the drawings, but arein the upper part of the loom from which the warp is led downward aroundthe rcarglass bars R, where the principal difficulty occurs which thisinvention remedies. Then the warp passes toward the front of the loomthrough the back reed, (not shown,) through the eyes of the heddles H,thence through the reed RQ, which is the ultimate distributer of thewarp and the instrument by which the warp is beaten up and closed inweaving.

The web of the finished material is formed and begins at W and passesover the front glass bar G at the front of the loom to theregulator-roll C, which in ribbon-weaving is the substitute for thecloth-beam in. clothweaving. Above the regulator-roll G is thepressure-roll P, whichmaintains the tension. This regulator-roll C isslowly actuated by the ratchet connected with the power which drives theloom to apply proper tension to the material as the web is augmented at1V.

A strip of wood A is fastened to the lower part of the lathe B below theshuttle-race and projecting forward from the batten perhaps two inches;but it is adjusted to stand out from the batten just far enough todeliver a light tap to the web between the glass rod at IOO C below justin advance of the impulse of the batten striking the weft home, asillustrated in dotted lines in Fig. 1. This slat attached to the lathenot only administers a blow to the web, but presses'it forward toincrease the tension, and I have attained the best results by timingthis blow and pressure just prior to each stroke of the reed. The sameresult might be less perfectly attained by an independent bar actuatedin any convenient manner independent of the motion of the lathe, whichshould administer a blow to the warp or to the warp-threads at any pointbetween the Warp-beam and the cloth-beam or which should deliver aslight blow to the glass bars themselves or to the frame of the loom, soas to dislodge the warp or the web from the bars; but the best manner inwhich I have contemplated using my improvement is bya slatattached tothe lower part of the lathe, which is a cheap and expeditious device forovercoming this difficulty in a most effectual way.

Figs. 2 and 3 illustrate a modification of my device which consists inmaking the attachment to the lathe in the form of a frame A', said framesurrounding the finished web. By this construction the same result isaccomplished as in that heretofore described,

the difference in operation being that the eenoss other constructionsmay be made to perform the same result in substantially the same way-as,for instance, practically the same result could be secured by strikingthe bars instead of the'material being woven. I consider all thesevarious and obvious arrangements as coming Within my invention anddiscovery.

Vhat I claim, and desire to secure by Letters Patent, is-

1. In a loom, the combination of the front and rear rods, and'means forloosening the material from said rods periodically, substantially asdescribed.

2. In a loom, the combination' of the front and rear rods and meansactuated by the lathe for loosening the material from said rodsperiodically, substantially as described.

3. The combination with a loom of a lathe having a projection thereon soplaced as to strike the web when the lathe swings, substantially asdescribed.

4. The combination with a loom having suitable means for guiding thewarp-threads both before and after the weft is incorporated of meansstriking said threads near one of said guiding means periodically,substantially as described.

In witness whereof I have hereunto set my hand, at New York, in thecounty of New York and State of New York, this 19th day of August, 1901.
